IMPROVEMENT IN RAlSIN-SEEDERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, WILLIS CURTIss, -Jr., of Weicottville, in the county of Litchfield and State of'Oonneoticut, have invented and made an Improvement in Raisin-Seeders; and the following is declared to be a correct description of the same.

This invention is for ejecting the seeds from raisins, and is an, improvement upon the raisin-seeder patented November 28, 1865, No. 51,201.

My improvement relates to an arrangement of slides actuated by a crank for operating the holdingjaw and ejecting-pins, so that the raisin can be more conveniently placed in the machine; the parts are much stronger and less liable tobe bent than in the machine patented as aforesaid, and the raisin is delivered by a revolving-sweep acting above the grating that supports the raisin, while the seeds are removed from the ejectors by a swinging scraper.

In the drawing- Figure 1 is an elevation with the bed in section;

Figure 2 is a vertical transverse section; and Figure 3 is an inverted plan with the legs removed. The vertical frame a is supported upon the feet I),

and from the side thereof the bed 0 or grating, upon which the raisin is placed, projects and is provided with a supporting-leg, d, and chute e.

The surface of I the grating c is raised above the upper end of the chute 0 so that the raisin will not catch against the end of the openings through the bed as the said raisin is moved out of the machine by a revolving sweep, hereafter described.

The holding-jawf projects above the bed and grating 0 from a frame, g, that ismounted in guides in the frame a so as to be moved up and down vertically, and the slide h, that is mounted in guides upon the frame g, is made with a projectingflange, it, that carries the ejecting-pins k, passing freely in holes in the j f- In these slides g and h arecain-sha'ped openings through which the crankpin t passes.

This crank-pin is upon a crank that revolves in a recess in the frame a.

At the end of the shaft 1 and 'm is a fly-wheel and handle for revolving the shaft'l and actuating the parts of the machine.

The shapes of the transverse cam-slots or openings in the frames or slides g h are such that the crank-pin in revolving, as indicated by the arrow, fig. 1, will lift them together, and then give a still furthegmovement to the frame h, flange It, and ejecting-pins k to draw them up from contact with the raisin that is between the holding-jaw f and grating c, and atthis point the sweep t, that extends as an arm from the crank-pin '5, passes between f and cand delivers the raisin into the trough e.

The attendant places another raisin upon the grating 0, and the further rotationof the fly-wheel and crank brings down the holding-jaw to confine the raisin, and then the ejecting-pins k are forced through such raisin and the seeds delivered through the grating 0.

At this time the swinging scraper '1': below the bed is actuated by a projection, w, upon the fly-wheel, and forces the seeds away from the ends of the ejeotors, and they rise and the operations-are repeated.

A cam projection, x, from the frame y, acts upon the swinging scraper as said frame g rises to return the scraper to a normal position.

I claim as my invention- 1. The slidesg and h in the frame a, carrying respectively the holding-jaw f and ejecting-pins It, in combination with the grating c for sustaining the raisin, as and for the purposes set forth.

2. The arrangement of the crank and pin '5, slides g and h, with their cam-shaped slots, and the sweep 2', for-removing the raisin, in the manner specified, whereby these parts are all actuated in proper time by one crank-pin.

3. The-scraper 'v, beneath the grating c, and actuated by the projection w upon the fly-whcel m and the cam on, projecting from the slide 9, as and for the purposes set forth. I Signed by me this 28th day of March, A. D. 1871.
